After disposing of it, the quality of water should attain the following standards: COD100mg/L,SS50mg/L,Chroma 40 times,reaching the B standard of (DB37/533-2005)of local standards of Shandong Province Textile industrial wa
4、ter pollutant discharge standards. The design of this project is in accordance with requirements of the environmental protection in the wastewater. It uses the hydrolytic acidification-SBR-coagulation-sedimentation process to deal with the wastewater in textile printing. Based on comparison of the detailed program, we select the following processes: Printing and Regulating Hydrolytic SBR dyeing wastewater Grids pond acidificationp
